2 official rulings from Bandai, last ruled Mar 28, 2024. Straight answers to how this card actually resolves.

I attack with my [Beelzemon Blast Mode]. Can I activate this card’s <Your Turn> effect?
No, you can't. This card can only be activated when you attack with a card explicitly named [Beelzemon].

I used [ST14-02]/[Impmon] to attack, and its <When Attacking> effect digivolved it into [Beelzemon] from my trash. At such times, can I use this card's effect to again digivolve [Beelzemon] into [Beelzemon: Blast Mode] in my trash?
Yes, you can.
